A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes.
In meteorology, the synoptic scale ... [10] During the day, ... On constant pressure upper level charts, it is located within the highest height line contour. ...
A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.
An automated prognostic chart of the 96-hour forecast of 850 mbar geopotential height and temperature from the Global Forecast System. Atmospheric models are computer programs that produce meteorological information, including prognostic charts, for future times at given locations and altitudes. [10]
The time of the day must be considered, as there are two natural rises per day (locally around 10 am and 10 pm) and two natural falls per day (locally around 4 am and 4 pm). These daily changes in pressure can mask the movement of pressure systems and fronts past a location.
Microsoft's Aurora system offers global 10-day weather and 5-day air pollution (CO 2, NO, NO 2, SO 2, O 3, and particulates) forecasts with claimed accuracy similar to physics-based models, but at orders-of-magnitude lower cost. Aurora was trained on more than a million hours of data from six weather/climate models. [83] [84]
An example of a forecast product from the GFS, in this case a 96-hour forecast of 850 mb geopotential height and temperature. The Global Forecast System (GFS) is a global numerical weather prediction system containing a global computer model and variational analysis run by the United States' National Weather Service (NWS).
The Todd Weather Folios are a collection of continental Australian synoptic charts that were published from 1879 to 1909. The charts were created by Sir Charles Todd's office at the Adelaide Observatory. In addition to the charts, the folios include clippings of newspaper articles and telegraphic and handwritten information about the weather.
